Modern Spa Covers was founded as Aztech Energy in 2016 to bring practical, cost-saving, solar and thermal technology solutions to market. We have five US patents pending in technologies as diverse as solar thermal energy, radiant heating and cooling of buildings, thermal energy storage, and, of course, solar heating of hot tubs. We changed our name to Modern Spa Covers in 2019 to better reflect our focus in the spa cover product market.
